If there is no change in the sea ice extent minimum, we both pay $1000. If extent drops 2 million sq. km, then Bastardi pays $2000 and I pay zero. If extent grows 2 million sq. km, then I pay 2k and Bastardi pays zero. If extent grows 3 million sq. km, then I pay 3k and Bastardi pays zero. Again, being very wrong is doubly costly.
